JOHN KING, CHARLES DOWNES, AND JOHN lVADDINGTON, OF BUENOS AYRES,ARGENTINE REPUBLIC.

FIRE-BAR SUPPORT AND DEFLECTOR.

SPECIFICATION forming part of Letters Patent N 0. 569,646, dated October20, 1896.

Application filed May 28, 189 6. Serial No. 593,468- (No model.)Patented in Argentine Republic November 6, 1895, No. 403.

To all whom it may concern-.-

Be it known that we, JOHN KING, CHARLES DowNns, and JOHN WADDINGTON,citizens of the Argentine Republic, residing atBuenos Ayres, in theArgentine Republic, have invented certain new and useful Improvements inSteam-Boilers, (for which wehave received Letters Patent in theArgentine Republic, No. 403, dated November 6, 1895,) of which thefollowing is a specification.

This invention relates to the fire-bar support and deflector of theboiler; and it consists in the novel construction and combination of theparts hereinafter fully described and claimed.

Figure 1 shows, as an example, a locomotivc-boiler fitted with thehollow water-space fire-bar carrier and hollow water-space dc flector.

Fig. 2 is an underneath View of Fig. 1.

Fig. 3 is a cross-section of Fig. 1.

Figs. 4, 5, and 6 show details of the waterspace fire-bar carrier, whichis made in the shape of the letter H, as shown on plan, Fig. 5, and ishollow throughout. In Fig. 5, 45 is the end next the fire-hole door, 40is the end next to the tube-plate, and 47 is the connecting-piecebetween 45 and 46. The water enters at 30 31, travels along 45 into 47and from there into 16, and out at 32 on top of carrier, where it enterspipe 29, Fig. 3, which is the pipe connecting the carrier and deflector,as will be more clearly seen on reference to Fig. 1. Fig. 6 shows thetwo ends and M3 in section, 48 being the water-space. The bars marked iiare shown in position, sitting on the seat ii). In Fig. 4 theconnecting-pipe 4:7 is shown in section with water-space through itmarked 48. On the bottom of the carrier are washout-plugs 50, Figs. 5and 6, and the connectingpiece i7 is arched (see dotted lines, Fig. 6)to give strength.

Figs. 7, S, 9, and 10 illustrate details of the deflector, showing theform in which it is constructed. It consists of a hollow metal caseadequately stayed to withstand steam-pressure. On the end section, Fig.8, and on the reverse plan, Fig. 10, 33 is where the connecting-pipe 29,Fig. l, is screwed into the deflector. In Figs. 7 and 8, 34: and 35 arewhere pipes 27 and 28, Fig. 1, are screwed into the deflect-or, and 52,Fig. 8, are stays. In Figs. 7, 8, 9, and 10, 51 are washout-plugs.

Figs. 11, 12, and 13 illustrate details of twin clack and circulationvalve combined, marked 4: and 5 in Figs. 1 and 2. In Fig. 11, which is afront sectional elevation, the clack-valve for injector 7, Fig. 3, ismarked 53. The clack-valve for pump 3, Figs. 1 and 2, is marked 51. Theoutlet to circulation and feed pipe 21'l-is marked it, and the outlet tocirculation-valve 5, Fig. 3, is marked 55. In Fig. 12, which is a sideelevation, let is the outlet to the circulation and feed pipe 2i, Figs.1 and 2, and 54 is the inlet from. pump 3, Figs. land 2. 5 is thecirculation-valve. 5G is the flange for connecting to boiler. In Fig.13, which is a sectional plan of the valve, is the inlet from theclack-box and 57 is the outlet to the boiler.

The same numbers refer to the same parts in the several figures of thedrawings.

1 is the hollow water-space fire-bar carrier.

2 is the hollow water-space deflector.

3 is the pump.

4 is the double clack for pump and injector.

5 is the circulation-valve between clack el and boiler.

0 is the stopwalve; 7, the inject-or for carrier and deflector; S, thesupplementary injector for direct feed to boiler, and 9 a fourway piececonnecting the feed or circulation pipe 24: to the carrier 1.

10 is a blow-down cock, and 11 a two-way cock for the passage of waterfrom the tender (shown at the extreme left in Figs. 1 and to the pump orinjector 8.

12 is a steam-escape and scum-cock combined, and 13 is a valveregulating circulation between the deflector 2 and the boiler.

14, Fig. 1, is the injector steanrcock, and

15 a handle on the foot-platc for working the circulationwalve 5, Fig.2.

16, Fig. 1, is a handle on the foot-plate for working the blow-down cock10, and 17 is a handle on the foot-plate for working the twoway cock 11.

18, Fig. 2, is the feed-pipe from the tender to the two-way cock 11, and19 is the feedpipe from the two-way cook 11 to pump 3.

20 is the feed-pipe from two-way cock 11 to injector 8, and 21 thefeed-pipe from the tender to injector 7.

22 is the pipe from injector 7 to clack 4, 23 pipe from pump 3 to clack4, and 24 feed and circulation pipe from clack 4 to carrier 1.

25 and 26 are pipes from the four-way piece 7 9 to the carrier 1.

27 is a pipe leading from the deflector 2 to the boiler through valve12, and 28 a pipe leading from the deflector to the boiler through valve13.

29 is a pipe connecting the carrier 1 and deflector 2, screwed into thelatter at 33, Fig. 1, and screwed to the former by a couplingnut at 32.

30 31 are the points where the pipes 25 and 26 are connected with thecarrier 1, and 32 is where the pipe 29 is connected to the carrier. 33is where pipe 29 is connected to the deflector 2, 34 is where the pipe27 enters said deflector, and 35 where the pipe 28 enters the $31118.

36, 37, and 38 arehollow studs screwed into the fire-box supporting thedeflector 2. 39 and 40 are plates bolted to foundation-ring of fire-boxsupporting carrier 1.

41 are the fire-bars.

Pipes 27 and 28 are carried by means of expanded tubes 42 43 through thewalls of the fire-box and outside the shell.

The working of our invention is as follows: When the pump is supplyingwater to the boiler, the water enters from the tender by pipe 18 andpasses through two-way cook 11 to the pump 3 by pipe 19, then passesinto pipe 23 through clack 4 into feed and circulation pipe 24 at 44,from whence it passes through four-way piece 9 into bottom of carrier 1at 30 31, leaving same at 32 and passing into deflector 2 at throughpipe 29, then passing into pipes 27 and 28 at 34 and 35 and finallyentering the boiler at valves 12 and 13. During the time the pump 3 isworking the cock 5 is closed to boiler. When the injector 7, carryingwater to carrier and deflector, is working, the water is drawn from thetender through pipe 21 and passed into pipe 22 to clack 4, from whenceit passes into pipe 24 at 44, after which it follows the same course asdescribed when the pump is working. During the time injector 7 isworking circulation-valve 5 is closed to boiler. If necessary, pump 3and injector 7 can be worked simultaneously. \Vhen required, thefeed-water from pump 3 or injector 7 can be passed direct into theboiler by opening valve 5 and closing stop-valve 6 on pipe 24, leadingto carrier 1.

In using the carrier and deflector as a means of generating steam onlyit is necessary to open valve 5 to boiler, so giving the water acomplete circulation through the carrier and deflector, the waterfollowing the same course as previously described when pump .andinjector are working.

In the event of having to work the supplementary injector 8 the two-waycook 11 is closed to pump 3 and opened to injector 8, which feeds theboiler through the ordinary clack.

The carrier 1 and deflector 2 may be made I of iron, steel, copper,brass, or other suitable metal and may be either cast or made of platemetal and riveted, as desired. The deflector may be made fiat, as shown011 the drawings, or arched, according to circumstances.

Having fully described our invention, what we claim, and desire tosecure by Letters Patent, is-

In a boiler, the combination, with a hollow In testimony whereof we havehereunto affixed our signatures in the presence of two witnesses.
